ENGLISH
• The demolition hammer crankshaft is lubricated with
low viscosity grease so that it can be used for a long
period without the need to replace the grease.
• Go to a Authorized Service Center
to replace the grease in case of leakage.
Applying non-recommended grease
will stick to the machine and reduce it useful life.
• Clean the machine with a soft cloth, moistened with soap
and water, preferably after each use.
• Always keep the vents clean and unobstructed to ensure
proper engine cooling.
• Regularly inspect all mounting screws and make sure
they are properly tightened. If any of the screws are loose,
tighten them immediately.
• The carbon brushes must be checked periodically, and
always replaced by a Authorized
Service Center when they have worn out.
• After they have been replaced, ask for them to inspect if
the new carbon brushes can move freely in the carbon
holder and ask them to turn the tool on for 5 minutes to
match the contact of the brushes and the switch.
• Only original spare carbon brushes
should be used, specifically designed with the right
hardness and electrical resistance for each type of motor.
Out-of-spec coals can damage the engine.
• When changing carbon brushes always replace both
coals.
• Servicing of the tools must be performed only at a
Authorized Service Center. Service
and maintenance by unqualified persons can be
dangerous and can cause personal injury in addition to
invalidating the product warranty.
